Sadly none of these works. There is a zprops_csgo by fransisco which working with CS:GO but.
There is two big problem.
1.The prop has terrible physics. If 2 prop like barrel contact with each other they "shoots out" each other.
2.In zombie mod for zombie maps its the best way if you can prop below yourself. I mean you look to below yourself to the ground jump and prop one barrel, then a second to go higher and be able to jump on roof.
But with that plugin you only can prop to front of yourself.
